In the embodiment shown in FIG. 1, a display device 1 displays created documents and guide information, and a flexible disk drive device 2 records information displayed on the display device 1 and reproduces already recorded information. , an input device 3 for inputting document creation information while displaying it on the display device 1; a printer device 4 for printing information displayed on the display device 1 and information reproduced from the flexible disk drive device 2; A word processor 6 includes a display device 1, a flexible disk drive device 2, an input device 3, and a printer device 4 connected thereto, and a control device 5 that controls the operation of each device.

In the configuration shown in FIG. 1, when the word processor 6 is powered on, the initial setting program built in the control device 5 is started, and the control device 5
After checking the functions in the system, start the system program. When the loading of the system program is completed in this manner, the word processor 6 becomes usable, and a document is created on the display device 1 by the operator's key input from the input device 3. The created document is stored on a flexible disk (hereinafter referred to as a floppy disk) set in the flexible disk drive device 2 as needed.
and is printed by the printer device 4.

Next, the present invention will be explained in detail with reference to the drawings. In the embodiment of the present invention, descriptions of the same components as those shown in FIG. 1 will be omitted.

FIG. 2 is a block diagram showing one embodiment of the control device provided in the word processor of the present invention.
In FIG. 2, there is a control section 51 that connects each device constituting the word processor 6 and controls the operation of each device, and a control section 51 that is built in the control section 51 and detects the number of connected flexible disk drive devices 2. A power supply section 53 that supplies power to the connected number detection mechanism 52 and each device constituting the word processor 6.
A control device 5A is constructed from these. In this embodiment, the display device 1 and the flexible disk drive device 2 are mounted within the housing of the control device 5A.

FIG. 3 is a flow chart for explaining the operation of one embodiment of the word processor of the present invention. In FIG. 3, when the power is turned on in step 30 to start the system of the word processor 6, the initial setting program built in the control unit 51 is started in step 31, and a function check inside the control unit 51 is executed. be done. Next, in step 32, the number of connected flexible disk drives 2 is checked and read. This checking method is performed, for example, by the control unit 5.
The number of connected flexible disk drive devices 2 can be recognized by a program by setting a switch built into the flexible disk drive device 1. Then, in step 33, the number N of connected flexible disk drive devices 2 is set, and in step 34, as a result of determining N,
When is 1, system program 1 is activated in step 39.

However, if N is not 1 as a result of determining N in step 34, it is determined in step 35 whether N is 2. If N is 2, system program 2 is activated in step 40.

Then, in step 35, if N is not 2 as a result of the determination, the process proceeds to the next step and the same process as described above is repeated. Next, in step 36, it is determined whether N is (k-1). When N is (k-1), the system program (k-1) is activated in step 41.

However, if N is not (k-1) as a result of the determination in step 36, then in step 37 the system program k is activated.

Therefore steps 37, 39, 40 and 4
In step 1, a system program suitable for the configuration is activated according to the number of connected flexible disk drive devices 2, so that one word processor 6 can be used in various ways. Then, in step 38, loading of the system program is completed and the word processor 6 is loaded.
becomes available.

FIG. 4 is a flowchart for explaining an example of the use of the word processor of the present invention. Fourth
In the figure, the word processor 6 generally includes:
There are floppies as information media on which three types of information are recorded, one being a program floppy 7 on which a system program for realizing the functions of the word processor 6 is recorded. The other is a dictionary floppy disk 8 which stores a dictionary for converting words input in hiragana into kanji when a document is created using the word processor 6. The remaining one is a document floppy disk 9 for storing documents created by the word processor 6. These floppies 7, 8 and 9 are all driven by the flexible disk drive 2 when the word processor 6 is used.

Therefore, the operation method differs depending on the number of flexible disk drive devices 2 connected.

The word processor 6 is the system program 1
When started, since there is only one flexible disk drive device 2 (FDD 2A), the operation is as follows. In step 61, first
Set the program floppy disk 7 on FDD2A,
In step 62, system program 1 is loaded. Next, in step 63,
After taking out the program floppy 7 from the FDD 2A and setting the dictionary floppy 8, a document is created and edited in step 64. Here, in step 65, the dictionary floppy 8 is taken out from the FDD 2A, and after the program floppy 7 is set, the document registration program is loaded in step 66. Then, in step 67, the program floppy 7 is taken out from the FDD 2A, and after the document floppy 9 is set, the document is registered in the document floppy 9 in step 68. Next, in step 69, the FDD
After the document floppy disk 9 is taken out from 2A and the program floppy disk 7 is set, a document printing program is loaded in step 70. Therefore, in step 71, the program floppy 7 is taken out from the FDD 2A, the document floppy 9 is set, and the document is printed on the printer device 4 in step 72.

Therefore, when creating, registering and printing documents, each floppy disk 7,
Although the number of replacements for parts 8 and 9 is increased, the system can be configured at low cost.

Furthermore, when the word processor 6 is started by the system program 2, there are two flexible disk drive devices 2 (FDD2A and FDD2B).
Therefore, the operation is as follows. Step 81
First, the program floppy 7 is set in the FDD 2A, and the system program 2 is loaded in step 82. Next, step 8
In step 3, the program floppy 7 is taken out from the FDD 2A, and the dictionary floppy 8 is set.In step 84, the document floppy 9 is set in the FDD 2B. Here, step 85
After creating and editing the document in Step 86
The document is registered in the document floppy disk 9 at . Then, in step 87, the dictionary floppy 8 is taken out from the FDD 2A, and after the program floppy 7 is set, a document printing program is loaded in step 88. Next, in step 89, the document is printed on the printer device 4.

Therefore, when creating, registering, printing, etc. documents, there are two devices, FDD2A and FDD2B.
Leave the document floppy disk 9 set,
It is only necessary to replace the program floppy 7 and the dictionary floppy 8, resulting in a very user-friendly system.

Further, when the word processor 6 is started by the system program 3, the flexible disk drive devices 2 are three (FDD2A, FDD2B).
and FDD2C), so the operation is as follows. In step 91, the program floppy disk 7 is first set on the FDD 2A, and then in step 92
At this point, the dictionary floppy disk 8 is set on the FDD 2B. Next, in step 93, the FDD is
After setting the document floppy disk 9 on the 2C, the system program 3 is loaded in step 94. Here, in step 95 it is determined whether there is another document to be printed, and if it is necessary to print another document, in step 96 a new document is printed while printing the other document on the printer device 4. Create and edit. However, if no other document is to be printed, only a new document is edited in step 99. Then, in step 97, the document is registered on the document floppy disk 9. Next, in step 98, the document is printed on the printer device 4.

Therefore, when creating, registering, printing, etc. a document, each floppy disk 7, 8, and 9 should be set as they are because there are three devices, FDD2A, FDD2B, and FDD2C, and while creating a new document, the previous It is also possible to perform so-called parallel processing in which created documents are printed at the same time, and the utilization efficiency of the word processor 6 is dramatically improved.

Furthermore, when the word processor 6 is started by the system program 4, there are four flexible disk drives 2 (FFD2A, FFD2B,
FFD2C and FFD2D), each floppy disk 7, 8, and 9 are set as they are, and the already created document floppy disk is set in the remaining one, and the contents can be exchanged between the already created document floppy disk and the document floppy disk 9. The word processor 6 can be used in a wide range of applications.

FIG. 5 is a block diagram for explaining the relationship between a flexible disk drive and a floppy disk. In FIG. 5, when there is only one flexible disk drive device 2, each floppy disk drive 7, 8, and 9 are all driven by the FDD 2A and must be replaced each time.

However, when there are two flexible disk drives 2, the program floppy 7 and the dictionary floppy 8 are driven by the FFD 2A.
Since the document floppy 9 is driven by the FDD 2B, only the program floppy 7 and the dictionary floppy 8 need to be replaced.

When there are three flexible disk drive devices 2, the program floppy 7 is connected to the FDD 2A, the dictionary floppy 8 is connected to the FDD 2B, and the document floppy 9 is connected to the FDD 2C.
is driven, so there is no need to replace each floppy disk.

In this way, by activating the system program according to the number of connected flexible disk drive devices, functions can be automatically switched, thereby making it possible to provide a word processor that meets the user's needs.

〔Effect of the invention〕

As can be easily understood from the above, the present invention provides a control device with a connected number detection mechanism capable of detecting the number of connected flexible disk drive devices, checks the number of connected flexible disk drive devices by a program, and adjusts the functional range according to the number of connected flexible disk drive devices. Since we decided to selectively load the system program corresponding to the above check result using a program flexible disk in which a system program that has been determined has been recorded in advance, when the word processor system is started, it is possible to load the system program according to the number of connected flexible disk drive devices. Since the functions are automatically switched by starting the system program, the system can be expanded in response to the user's workload, and has the advantage of being highly flexible.

In addition, when creating a series of devices, the number of FDDs connected is a major factor in discriminating models;
It is possible to expand the series by changing the number of connected devices using one type of flexible disk for programming, and it also has the effect of being rich in diversity.
